Rigidbody.AddForce

Parameters

Description

Adds a force to the rigidbody.

Force can be applied only to an active rigidbody. If a GameObject is inactive, AddForce has no effect.

Wakes up the Rigidbody by default. If the force size is zero then the Rigidbody will not be woken up.

See Also: AddForceAtPosition, AddRelativeForce, AddTorque.

// Add a thrust force to push an object in its current forward
// direction (to simulate a rocket motor, say).
var thrust: float;
var rb: Rigidbody;

function Start() {
	rb = GetComponent.<Rigidbody>();
}

function FixedUpdate () {
	rb.AddForce(transform.forward * thrust);
}

using UnityEngine;
using System.Collections;

public class ExampleClass : MonoBehaviour {
    public float thrust;
    public Rigidbody rb;
    void Start() {
        rb = GetComponent<Rigidbody>();
    }
    void FixedUpdate() {
        rb.AddForce(transform.forward * thrust);
    }
}
